This results in poor bending and torsional stiffness and poor handling performance. In addition, the front end of the body shotgun structure is a welded structure composed of multiple stamped parts, which is complex in structure and process and difficult to control in terms of assembly dimensions.

[0046] This application provides a vehicle body shotgun structure, and also provides a vehicle including the above-described vehicle body shotgun structure.

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] like Figure 1-7As shown, a vehicle body shotgun structure is a longitudinal beam on a vehicle that mounts a front fender. Located on the outermost side of the driver's cab, it is used to enhance the vehicle's structural strength and for impact cushioning. Optionally, two vehicle body shotgun structures are symmetrically arranged along the width of the vehicle. The vehicle body shotgun structure includes a shotgun beam body and a bracket assembly 3. The shotgun beam body includes a tubular shotgun front beam 1, which includes a first front end 11 near the frame longitudinal beam 7. The bracket assembly 3 is fixed to the frame longitudinal beam 7 and includes a first bracket 31. The first bracket 31 enables an adjustable rigid connection of the first front end 11 of the shotgun front beam 1, thereby enabling an adjustable rigid connection of the shotgun beam body on the frame longitudinal beam 7.

[0049] It should be noted that the shotgun beam body can also be called the upper longitudinal beam. The rear end of the shotgun beam body away from the frame longitudinal beam 7 can be connected to the vehicle's A-pillar or the vehicle's floor crossbeam.

[0050] The first bracket 31 can be made of sheet metal. The bracket assembly 3 may consist only of the first bracket 31, in which case the first bracket 31 is directly fixed to the longitudinal beam 7 of the frame; of course, the first bracket 31 may also include other structural components, in which case the first bracket 31 is fixed to the longitudinal beam 7 of the frame through the other structural components included in the bracket assembly 3.

[0051] "Adjustable position" means that the assembly position of the first front end 11 relative to the first bracket 31 along the axial direction of the first front end 11 can be adjusted according to actual needs to meet the assembly connection between the first front end 11 and the first bracket 31. "Rigid connection" means that the fixed connection between the first front end 11 and the first bracket 31 is a rigid connection, that is, there is no elastic buffer at the connection between the first front end 11 and the first bracket 31, and the two are firmly and rigidly connected together.

[0052] Please see the appendix Figure 3 The axial direction of the first front end 11, i.e., the attachment Figure 3 The direction indicated by the middle arrow.

[0053] The shotgun front beam 1 of this application is no longer composed of multiple stamped parts welded together, but is formed by an integrally molded tubular structure. It is not only simple in structure and convenient and quick to process and manufacture, but also easy to control the size of the shotgun front beam 1 to meet the assembly size requirements during later assembly.

[0054] Furthermore, the first front end 11 of the shotgun front beam 1 is fixedly connected to the frame longitudinal beam 7 through the first bracket 31. The connection between the first front end 11 and the frame longitudinal beam 7 is no longer a soft connection, but a hard connection, which improves the bending and torsional stiffness / modal of the whole vehicle, and enhances handling stability and comfort. Moreover, the position of the first front end 11 relative to the first bracket 31 is adjustable, providing adjustment margin for the assembly between the two, compensating for minor deviations in component dimensions, and reducing dependence on machining accuracy.

[0055] It should be further explained that the first front end 11 is detachably connected to the first bracket 31, thereby realizing the detachable rigid connection of the shotgun beam body on the longitudinal beam 7 of the frame.

[0056] Please see the appendix Figure 3-4 In some embodiments of this application, a first support 31 is formed with a first surrounding portion 311 along the circumferential direction of the first front end 11, and the first front end 11 and the first surrounding portion 311 are sleeved together.

[0057] It should be noted that in some embodiments, the first front end 11 is fitted inside the first surrounding portion 311; in other embodiments, the first front end 11 is fitted outside the first surrounding portion 311. Preferably, the first front end 11 is fitted inside the first surrounding portion 311.

[0058] By setting the first surrounding part 311, the first front end 11 is fitted and connected in the circumferential direction, ensuring the contact area between the first surrounding part 311 and the first front end 11, thereby effectively ensuring the reliability and stability of the hard connection between the two and preventing shaking or separation during use.

[0059] It should be noted that, in addition to the structure including the first surrounding part 311, the first bracket 31 can also be configured in other forms. For example, the first bracket 31 includes a first connecting part that is perpendicular to the axis of the first front end 11, and correspondingly, the first front end 11 is provided with a second connecting part that is perpendicular to the axis of the first front end 11. Through the alignment and fitting of the first connecting part and the second connecting part, a hard connection between the first front end 11 and the first bracket 31 is achieved.

[0060] Please see the appendix Figure 4 In some embodiments of this application, the first front end 11 has a first mounting hole. The first surrounding portion 311 has a second mounting hole that matches the first mounting hole. A first fastener 4 passes through the first mounting hole and the second mounting hole respectively to achieve a hard connection between the first front end 11 and the first surrounding portion 311.

[0061] It should be noted that the first fastener 4 can be a fastening pin or a fastening bolt.

[0062] As described above, this ensures the reliable and stable connection between the first front end 11 and the first surrounding part 311, thereby ensuring the reliable and stable connection of the shotgun front beam 1 to the first bracket 31. The shotgun front beam 1 will not shake or detach relative to the first bracket 31.

[0063] Furthermore, it enables a convenient and quick detachable connection between the first front end 11 and the first surrounding part 311, facilitating the disassembly, replacement, and maintenance of the shotgun front beam 1 on the first bracket 31.

[0064] It should be noted that, in addition to providing a first mounting hole at the first front end 11 and a second mounting hole at the first surrounding portion 311, and achieving a detachable connection between the two through the first fastener 4, other configurations are also possible. For example, a locking member capable of locking and closing along its own circumference is provided; along the axial direction of the first front end 11, the upper half of the locking member is sleeved around the circumference of the first front end 11, and the lower half of the locking member is sleeved around the circumference of the first surrounding portion 311. The locking and closing or unlocking of the locking member achieves the locking and fixing connection or the unlocking and fixing of the first front end 11 and the first surrounding portion 311.

[0065] In some embodiments of this application, the diameter of the first mounting hole or the second mounting hole along the axial direction of the first front end 11 is larger than the outer diameter of the first fastener 4, so as to make the position of the first front end 11 relative to the first surrounding part 311 adjustable.

[0066] It should be noted that the diameter of one of the first mounting holes and the second mounting hole is larger than the outer diameter of the first fastener 4, while the other hole is adapted to the outer diameter of the first fastener 4. As described above, a through-hole structure is formed. This structure is simple and allows the first front end 11 to have a certain adjustment margin along its axial direction. This avoids the problem of the first front end 11 and the first surrounding part 311 being unable to be assembled due to dimensional errors, compensates for minor deviations in component dimensions, and reduces the dependence on machining accuracy.

[0067] In some embodiments, please refer to the appendix. Figure 4 In some embodiments of this application, the first surrounding portion 311 has a U-shaped structure along the circumference of the first front end 11. Each surrounding surface of the first surrounding portion 311 is provided with a plurality of second mounting holes.

[0068] It should be noted that the first front end 11 can be either inside the first surrounding part 311 of the U-shaped structure or outside the first surrounding part 311 of the U-shaped structure.

[0069] Preferably, the first front end 11 is fitted inside the first surrounding part 311 of the U-shaped structure. Along the circumference of the first front end 11, the first surrounding part 311 of the U-shaped structure covers the first front end 11 on three sides, ensuring the circumferential covering effect of the first surrounding part 311 and the first front end 11. In addition, the first surrounding part 311 of the U-shaped structure also has an open opening to facilitate the fitting and disassembly of the first front end 11 into the first surrounding part 311, thus realizing the convenience of the assembly operation of the two.

[0070] Furthermore, the first surrounding portion 311 of the U-shaped structure includes a first wall, a second wall, and a third wall located on opposite sides of the first wall; along the axial direction of the first front end 11, the first wall has two second mounting holes, and the first wall and the second wall each have one second mounting hole. As described above, four mounting points are achieved for the hard connection between the first surrounding portion 311 and the first front end 11, that is, the first surrounding portion 311 and the first front end 11 are fully, reliably, and securely hard connected through the combined fastening action of the four first fasteners 4.

[0071] It should be noted that, in addition to being configured as a U-shaped structure, the first surrounding part 311 can also be configured in other forms. For example, the first surrounding part 311 can be a ring structure to achieve a circumferential ring-shaped fit to the first front end 11.

[0072] Please see the appendix Figure 3 In some embodiments of this application, the bracket assembly 3 includes a second bracket 32 ​​and a frame longitudinal beam bracket 33. The second bracket 32 ​​is fixedly connected to the first bracket 31. The frame longitudinal beam bracket 33 is fixedly installed on the frame longitudinal beam 7 and is detachably connected to the second bracket 32.

[0073] It should be noted that the first bracket 31, the second bracket 32, and the frame longitudinal beam bracket 33 are all sheet metal structures. The bracket assembly 3 is divided into two groups, with the first bracket 31 and the second bracket 32 ​​forming one group, and the frame longitudinal beam bracket 33 forming its own group.

[0074] The first bracket 31 and the second bracket 32 ​​are welded together; furthermore, the first bracket 31 and the second bracket 32 ​​are connected by CO2 welding (i.e., carbon dioxide shielded welding, a type of arc welding, which uses the high temperature generated by the electric arc to melt the metal to achieve welding; CO2 gas is used as a shielding gas, covering the electric arc and the molten pool to prevent oxygen and nitrogen in the air from entering the molten pool, avoiding oxidation and nitriding, and ensuring the quality of the weld). Further, the frame longitudinal beam bracket 33 is welded to the frame longitudinal beam 7, and is welded to one side of the frame longitudinal beam 7 along the vehicle width direction.

[0075] The frame longitudinal beam bracket 33 is fixed to the frame longitudinal beam 7, providing installation positioning for installing other structural components on the frame longitudinal beam 7; the first bracket 31 and the second bracket 32 ​​are fixed as one piece, providing an installation point for connecting with the frame longitudinal beam bracket 33 on the one hand, and an installation point for connecting with the shotgun front beam 1 on the other hand. As shown above, a hard connection between the shotgun front beam 1 and the frame longitudinal beam bracket 33 is achieved conveniently and quickly, thereby achieving a hard connection between the shotgun front beam 1 and the frame longitudinal beam 7.

[0076] Furthermore, the first bracket 31 and the second bracket 32 ​​are designed as separate components, which not only facilitates the production and processing of each component but also reduces transportation and storage costs. The first bracket 31 and the second bracket 32 ​​are fixed as one unit and can be detached from the shotgun front beam 1 and the frame longitudinal beam bracket 33, respectively. As such, the first bracket 31 and the second bracket 32 ​​of appropriate size can be selected and replaced according to actual needs to adapt to the size of the shotgun front beam 1 for specific requirements, greatly improving flexibility and applicability.

[0077] Please see the appendix Figure 3 , 5 In some embodiments of this application, the bracket assembly 3 further includes a first sleeve 34. Along the axial direction of the first front end 11, the frame longitudinal beam bracket 33 forms an accommodating space, and the first sleeve 34 is fixed to the accommodating space. A second fastener 5 passes through the first sleeve 34 and the second bracket 32 ​​in sequence to achieve a detachable connection between the frame longitudinal beam bracket 33 and the second bracket 32.

[0078] It should be noted that the first sleeve 34 has a threaded hole with internal threads. The frame longitudinal beam support 33 is a frame structure with internal accommodating space. Along the axial direction of the first sleeve 34, the frame longitudinal beam support 33 includes a bottom wall and a top wall, with one end of the first sleeve 34 fixed to the bottom wall and the other end fixed to the top wall. The bottom wall and top wall of the frame longitudinal beam support 33 are respectively provided with a first connecting hole and a second connecting hole; both the first connecting hole and the second connecting hole communicate with the internal threaded hole of the first sleeve 34. The second support 32 is provided with a third connecting hole that communicates with the second connecting hole. Along the axial direction of the first sleeve 34 (i.e., the axial direction of the first front end 11), and from bottom to top, the second fastener 5 passes through the first connecting hole, the internal threaded hole of the first sleeve 34, the second connecting hole, and the third connecting hole in sequence, so as to fix the first sleeve 34 on the second support 32, thereby realizing the fixed connection between the frame longitudinal beam support 33 and the second support 32.

[0079] It should be further explained that the second fastener 5 can be a fastening pin or a fastening bolt. When the second fastener 5 is a fastening bolt, the third connecting hole on the second bracket 32 ​​can be a threaded hole with internal threads to achieve the tightening and fixing of the second fastener on the second bracket 32; of course, the third connecting hole on the second bracket 32 ​​can also be a circular through hole, and a first connecting nut 35 communicating with the third connecting hole is provided on the second bracket 32 ​​to achieve the tightening and fixing of the second fastener 5 on the first connecting nut 35. Furthermore, a first washer is provided between the second fastener 5 and the bottom wall of the frame longitudinal beam bracket 33.

[0080] As shown above, its structure is simple, realizing the detachable connection between the frame longitudinal beam support 33 and the second support 32, which facilitates the disassembly, replacement and maintenance of the second support 32 on the frame longitudinal beam support 33; and, by setting the first sleeve 34, the connection strength between the frame longitudinal beam support 33 and the second support 32 is reliably increased, thereby ensuring the reliable and stable connection of the shotgun front beam 1 on the frame longitudinal beam 7.

[0081] Please see the appendix Figure 5 In some embodiments, the second bracket 32 ​​has a first docking portion 321. The frame longitudinal beam bracket 33 has a second docking portion 331, which is aligned and fitted with the first docking portion 321 and is perpendicular to the axial direction of the first front end 11.

[0082] It should be noted that the second docking part 331 is the top wall of the frame longitudinal beam support 33. Through the alignment and fit of the first docking part 321 and the second docking part 331, a reliable contact area between the second support 32 and the frame longitudinal beam support 33 can be ensured, thereby ensuring the reliability and stability of the connection between the second support 32 and the frame longitudinal beam support 33.

[0083] In some embodiments of this application, the shotgun beam body further includes a shotgun rear beam 2. The shotgun front beam 1, along its extending direction, includes a first front end 11 and a first rear end 12; the shotgun rear beam 2, along its extending direction, includes a second front end 21 and a second rear end. The second front end 21 forms a second surrounding portion 211; the second surrounding portion 211 and the first rear end 12 are sleeved together and fixedly connected.

[0084] It should be noted that in some embodiments, the first rear end 12 is fitted inside the second surrounding portion 211; in other embodiments, the first rear end 12 is fitted outside the second surrounding portion 211. Preferably, the second front end 21 is fitted inside the second surrounding portion 211.

[0085] The shotgun front beam 1 and shotgun rear beam 2 are designed as separate components, which not only facilitates the production and processing of each component but also reduces transportation and storage costs. Furthermore, the second surrounding part 211 achieves a circumferential fit and connection with the first rear end 12, ensuring the contact area between the second surrounding part 211 and the first rear end 12, thereby effectively guaranteeing the stability and reliability of the fixed connection between the two and preventing shaking or detachment during use.

[0086] In some embodiments of this application, a third fastener 6 passes through the second surrounding portion 211 and the first rear end 12 radially to achieve a fixed connection between the second surrounding portion 211 and the first rear end 12.

[0087] It should be noted that the third fastener 6 can be a fastening pin or a fastening bolt.

[0088] The third fastener 6 enables a convenient and quick fixed connection between the second surrounding part 211 and the first rear end 12. Its structure is simple, easy to operate, and the connection is stable and reliable.

[0089] Please see the appendix Figure 6-7 In some embodiments of this application, along the circumferential direction of the first rear end 12, the second surrounding portion 211 includes a first surrounding plate 2111 and a second surrounding plate 2112 that are spaced apart and positioned opposite each other. A third fastener 6 passes through the first surrounding plate 2111 and the second surrounding plate 2112.

[0090] It should be noted that the first rear end 12 can be fitted inside the first enclosure 2111 and the second enclosure 2112, or it can be fitted outside the first enclosure 2111 and the second enclosure 2112.

[0091] Preferably, the first rear end 12 is fitted between the first enclosure plate 2111 and the second enclosure plate 2112 to achieve positioning and installation of the first rear end 12 between the first enclosure plate 2111 and the second enclosure plate 2112. The first enclosure plate 2111 has a third mounting hole and the second enclosure plate 2112 has a fourth mounting hole; the first rear end 12 includes a first region opposite to the first enclosure plate 2111 and a second region opposite to the second enclosure plate 2112, the first region has a fifth mounting hole and the second region has a sixth mounting hole; the third fastener 6 passes through the third mounting hole, the fifth mounting hole, the sixth mounting hole and the fourth mounting hole in sequence to achieve a fixed connection between the first enclosure plate 2111, the second enclosure plate 2112 and the first rear end 12.

[0092] The second surrounding part 211 is composed of a first surrounding plate 2111 and a second surrounding plate 2112 positioned opposite each other. Its structure is simple and easy to process and manufacture. It not only ensures a reliable contact area between the second surrounding part 211 and the first rear end 12, but also provides sufficient freedom for the first rear end 12 in the area along the circumference of the second surrounding part 211 excluding the first surrounding plate 2111 and the second surrounding plate 2112, so as to facilitate the fitting of the first rear end 12 into the second surrounding part 211, thus realizing the convenience of the assembly operation of the two.

[0093] Please see the appendix Figure 7 In some embodiments, a second sleeve 13 is provided inside the first rear end 12, and a third fastener 6 penetrates the second sleeve 13.

[0094] It should be noted that the second sleeve 13 has an internally threaded hole. One end of the second sleeve 13 is fixedly connected to the first region, and the other end is fixedly connected to the second region. The third fastener 6 passes through the third assembly hole, the fifth assembly hole, the internally threaded hole of the second sleeve 13, the sixth assembly hole, and the fourth assembly hole in sequence to achieve a fixed connection between the first enclosure plate 2111, the second enclosure plate 2112, and the first rear end plate 12.

[0095] Furthermore, when the third fastener 6 is a fastening bolt, the fourth mounting hole in the second enclosure 2112 can be a threaded hole with internal threads to achieve the tightening and fixing of the third fastener 6 on the second enclosure 2112; of course, the fourth mounting hole in the second enclosure 2112 can also be a circular through hole, and a second connecting nut 2113 communicating with the fourth mounting hole is provided on the second enclosure 2112 to achieve the tightening and fixing of the third fastener 6 on the second connecting nut 2113. Furthermore, a second washer is provided between the third fastener 6 and the first enclosure 2111.

[0096] By setting the second sleeve 13, the connection strength between the first rear end 12 and the second surrounding part 211 is improved, ensuring the reliability and stability of the connection between the two, and preventing shaking or detachment during use.

[0097] Please see the appendix Figure 6-7 In some embodiments, the first rear end 12 is fitted inside the second surrounding portion 211, and the second surrounding portion 211 has welding holes 2114 to achieve welding between the second surrounding portion 211 and the first rear end 12. Furthermore, both the first surrounding plate 2111 and the second surrounding plate 2112 have welding holes 2114, and each surrounding plate has multiple welding holes 2114.

[0098] Alternatively, the first rear end 12 is fitted onto the second surrounding portion 211, and the first rear end 12 has welding holes 2114 to achieve welding between the first rear end 12 and the second surrounding portion 211. Furthermore, welding holes 2114 are provided on both the first and second regions of the first rear end 12.

[0099] It should be noted that welding holes 2114 are respectively provided on both sides of the third fastener 6 along the axial direction of the first rear end 12; the second surrounding part 211 is connected to the first rear end 12 by CO2 welding, and the two form a welding connection area at the welding holes 2114. By providing welding holes 2114, a weld seam is provided for welding the second surrounding part 211 to the first rear end 12, ensuring the uniformity and consistency of the welding.

[0100] As mentioned above, the double protection of the third fastener 6 and welding further increases the connection strength between the first rear end 12 and the second surrounding part 211, making the fixed connection between the two more reliable and stable, and preventing shaking or falling off during use, thus ensuring the safety of the vehicle during driving.
